No doubt, no competition and not only do you not need to push your development cycles, you don't have to lower your prices either. I really wish AMD would come out with something new and exciting, push the envelope a ton and see how Nvidia responds.
Stop thinking about it so hard, wait for the 980Ti or 390x. Save a little more money and go all out. I will say my two heavily overclocked 780Ti's struggle a little in FC4 where the frames clearly dip below 60. Wait wait wait!
